Back when I played the game in January, I had no issues whatsoever. I played on the highest possible settings with relative ease, and had no problems.
Now, coming back to play in July, I continue to crash within 15 minutes of gameplay. It could be walking through an open field, looking at a building, or walking towards and into a building. No matter what, I always manage to crash, and I receive a message from windows saying "DayZ.exe has stopped working". This happens on both stable and experimental servers. This also happens on any kind of server, regardless of difficulty, population, ping, and location in-game.
The problem is not only limited to me, my friends also have these problems and are almost incapable of playing the game because of it.
